Keep address bar content when leaving temporarily

[kukuro]

Steps:

1. Type something into address bar, do not search.
2. Press Android Home Button, minimize Vivaldi.
3. Go back to Vivaldi, check address bar. It will be empty.

I think it is a Chromium-related problem because other browsers based on Chromium have the same behavior.

It's very annoying because sometimes I need to search a long text (for example, a phone number, a strange name), but I cannot remember the whole text. I want to input twice but Vivaldi always empty my first input.

While as far as I tested, Firefox, Samsung Browser, Opera do not empty address bar. I hope Vivaldi can do like these browsers...
